i of the tire.

As a general thing, the demountable rims .in commonuse are of the transplit type, and require `the aid'of a tool to contract and eX- pand them to admi-t ofthe application or removal of the vtireand the restoration of the rim to normal condition after they tire is applied. It frequently happens, however, that the automobilist is not in possession of the required tool Vat the time when he needs it, in which event it is'practically impossibler for him to make a tire change, and it is sometimes difficult even under best conditions to force the tire on the riml without the aid of other and special tools for that purpose. v One object offmy invention 1s to provide a dcmountablc rim, composed of separable sections, which overcomes theabove-mentioned objections to split rims of ordinary type,'

and which, admits ofthe ready application and removal of a tire without the use of `special tools. 'Y

A'furtherV object of my inventionis to provide ademountable rim which may be employedfor use also as a spare rim for carrying asparev tire, and which when the use of a spare tire is needed can be immediatelv applied to:` the vehicle wheeh j Y The invention consists of the features of construction, combination and arrangement `of parts, hereinafter ,fully described and claimed, reference being had to the accompanying drawing, in whlchzf Figure l is a side elevatiompartly in section, of, a demountable rim embodying .my invention, such view looking toward. the

inner side of the rim. l" Y vliipnire 2 is a cross sectionthroughthe rim on the line 2 2 of Figure 1.

Figure 3 is a cross section through the rim on the line 3-3 of Figure 1.

`tween the same Referring to the drawing, 'l designates 4the felly of a vehicle wheel, which may be madeof wood or metal and which is provided at intervals with transverse openingsfor the passage of fastening bolts 2. Arranged at the inner side of the felly l is a fixed annular abutment plate 3 having an outstanding flange 4 properly. curved in cross section to form a 'seat for the tire conlining flange on one member of the des mountable rim,ihereina ftcr described. The Hange l is offset at its point of juncture with the plate 3 so as .to provide an annular seat liange 5 and an abutment shoulder 6.. The

headed ends of the bolts extend through the plate 3 and bear thereon, and the shanks of the bolts project through the felly l and have threaded ends 7 projecting beyond the opposite side of said felly. The threaded Vends of the bolts are designed to receive the usual removable wedge lugs S, which hold the demountable rim in position on the felly, each wedge lug being removably fastened in position by a nut 9 applied to the threaded end of the bolt.

The demountable rim, constructed in accordance withmy invention, is composed of two rim members l() and ll carrying the tire retaining fianges l2 and 13. These tire retaining flanges l2 and 13 are disposed at the opposite sides of the -demountable rim to receive and engage the beads 141- at the opposite sides of the shoe of the pneumatic tire l5. whereby the tire is held in the demountable rim. Each rim member l() and ll consists of va continuous ring or annulus, the rim Vmem-` bers being coextensive in width with each other and of a width somewhat greater than the width of the felly l.' i

The rim member l() is arranged tounderlie the rim member ll and is disposed beand the outer face of the felly l, and the inner face of said rim memberl0 is providechon opposite sides of its longitudinal center. with annular series of spaced Vlugs or projections 16 to `rest upon the felly l and properly space said rimr member 10 fromthe felly. These spacing members 16 form an adequate bearing for `the demountable rim and tire .on theffelly and reducethe amount of surface of the rim section l0 contacting with the felly so as to eliminate all liability of said rim member 10 binding on the felly and oausingtrouble or diieulty in applying or removing itA The rim members 10 and 11 as thus constructed and arranged are disposed in overlappingI relations'hiL ltlie'iange 12 of the iini inembei' 11'b'eiiig`looated at the `outer side ot Athe Wheel and engaging the outer bead141'of the tiret, while the -iaiige 13 v4ofthe ri ir Y member bearsapgainst the iixed retaininfrA i flange 4- and seats-thereon at the inner side o-liiV the ielly and-receives and engages vthe inner( l() bead 14 or' the 'tire 15; 151s thiis eonsti'uoted,"
